Umauma Falls is a waterfall in Hawaii County, Hawaii. It sits roughly 9.0 km (5.6 mi) NNW of Pepeekeo.
The Umauma Falls are located on the Umauma River on the Big Island of Hawaii, approximately 16 miles (26 km) north of Hilo. They are unique in Hawaii as being a series of three waterfalls in close proximity. They are easily viewed from an overlook located on private botanical garden property accessible for a fee. The overlook was constructed in 1996 by Walter L. Wagner who was developing the World Botanical Gardens with the waterfalls overlook as part of the tourist attraction. Subsequently, the waterfall overlook ownership was transferred circa 2008, and access to the overlook is now through Umauma Experience (also a botanical garden), and not through World Botanical Gardens.From the Wikipedia article “Umauma Falls”, licensed under CC BY-SA 4.0.

Golden hour & blue hour by month
Waterfalls photograph best in soft, even light: overcast days, deep shade, or the hour after sunrise before direct sun hits the water. Bright sun on white water blows highlights and adds harsh contrast.

Local time (Pacific/Honolulu), including daylight saving time. Golden hour runs from about −4° to +6° solar altitude, so the morning golden hour begins during blue hour, before sunrise.
Milky Way & night sky
From Umauma Falls, the Milky Way core is visible in a dark sky from February through October. June gives the longest window (about 7.8 hours on a moonless night), and the core peaks around 41° above the southern horizon. Our light-pollution model puts the sky at about Bortle 3 (rural sky), good enough for detailed Milky Way images.

Window when the galactic core is at least 10° high during astronomical darkness on the 15th of each month. Pick nights within a few days of the new moon. Plan exact nights with the Milky Way planner.
Estimated sky darkness: 3 Bortle 3 — Rural sky. Some light domes sit on the horizon, but the Milky Way still looks complex overhead. Modeled zenith brightness ≈ 21.69 mag/arcsec².
Weather & best season
Long-term NASA satellite data for this area show January as the clearest month (about 50% average cloud cover) and March as the cloudiest (62%). August is the warmest month and February the coldest, which matters for gear, snow access and how long batteries last at night.

Photography tips for this waterfall
- Keep a microfiber cloth handy — spray drifts onto the lens, especially at the plunge pool.
- Bracket shutter speeds: 1/8 s, 1/2 s and 2 s give very different water textures and you can choose later.
- A 3-stop ND filter lets you use slow shutter speeds even when the light is bright.
- Shoot a vertical and a horizontal frame; tall falls often work better in portrait orientation.
- Bring a spare battery — cold weather and long exposures drain them fast.
Season: Peak flow is usually in late spring; autumn adds color around the falls, and winter can bring ice formations at colder locations.
Suggested gear: Tripod, Circular polarizer, 3–6 stop ND filter, Lens cloth, Waterproof footwear. Work out exposures with the depth of field, ND filter and NPF rule calculators.
